### Checking cluster health for maintenance

You may query the cluster probe endpoint to check if the node which received the request can be taken down for maintenance, if the server replies back '412 Precondition Failed' this means you will lose HA. '200 OK' means you are okay to proceed.

```
curl http://minio1:9001/minio/health/cluster?maintenance=true
HTTP/1.1 412 Precondition Failed
Accept-Ranges: bytes
Content-Length: 0
Server: MinIO
Vary: Origin

## Changelog since v1.10.11

### Other notable changes

* Updates defaultbackend to 1.5 ([#69381](https://github.com/kubernetes/kubernetes/pull/69381), [@bowei](https://github.com/bowei))
* Immediately close the other side of the connection when proxying. ([#67288](https://github.com/kubernetes/kubernetes/pull/67288), [@MHBauer](https://github.com/MHBauer))

- Kubelet: close a loophole where static pods could reference arbitrary ResourceClaims. The pods created by the kubelet then don't run due to a sanity check, but such references shouldn't be allowed regardless. ([#131844](https://github.com/kubernetes/kubernetes/pull/131844),...

- kube-controller-manager can now start the quota controller when discovery results can only be partially determined. ([#67433](https://github.com/kubernetes/kubernetes/pull/67433), [@deads2k](https://github.com/deads2k))
- Immediately close the other side of the connection when proxying. ([#67288](https://github.com/kubernetes/kubernetes/pull/67288), [@MHBauer](https://github.com/MHBauer))

* Switch JSON marshal/unmarshal to json-iterator library.  Performance should be close to previous with no generated code. ([#48287](https://github.com/kubernetes/kubernetes/pull/48287), [@thockin](https://github.com/thockin))

- Kubelet don't forcefully close active connections on heartbeat failures, using the http2 health check mechanism to detect broken connections. Users can force the previous behavior of the kubelet by setting the environment variable DISABLE_HTTP2. ([#108107](https://github.com/ku...

*   `import tensorflow` now goes much faster.
*   Adds a file cache to the GCS filesystem with configurable max staleness for
    file contents. This permits caching of file contents across close/open
    boundaries.
*   Added an axis parameter to `tf.gather`.
*   Added a `constant_values` keyword argument to `tf.pad`.
*   Adds `Dataset.interleave` transformation.

- find accounts whose group memberships have changed; access policies available to a credential are updated to reflect the change, i.e. they will lose any privileges associated with a group they are removed from, and gain any privileges associated with a group they are added to.

- When client certificate files are provided, reload files for new connections, and close connections when a certificate changes. ([#79083](https://github.com/kubernetes/kubernetes/pull/79083), [@jackkleeman](https://github.com/jackkleeman)) [SIG API Machinery, Auth, Node and Testing]
